Of course. That's what being good means - you do the right thing. You act morally. You know what morals are.
The catch of course is you only think you know what being good means, you only think you do the right thing, you only think you act morally and know what morals are and there are a lot of other people, like me, who think they know what being good means, think they do the right thing, think they act morally and know what morals are and yet they disagree with you on key points.
Personally I'm ok with that because I don't believe in absolute morals. You seem to not be ok with moral diversity. Is moral intolerance evil?
